CERTIFIED BY: Duncan Sanderson, B.Sc., Licensed Assayer of British Columbia INDEPENDENT GEOCHEMIST: Dr. Barry Smee., Ph.D., P. Geo. DATE OF CERTIFICATION: August 8, 2012 ORIGIN OF REFERENCE MATERIAL: Standard CDN-GS-2M was prepared using ore supplied by Barrick Gold Inc. from their Bald Mountain Mine in Nevada, USA. It is Carlin Style Mineralization in the prolific Battle Mountain-Eureka Trend in Northern Nevada, USA. The material is from breccias near the contact between the Mississippian Pilot Shale and the underlying Devonian Guilmette formation. Near the center of the system, micron-sized native Au occurs with base metal sulfides and sulfosalts. In peripheral deposits and in later stages of mineralization, Au is typically submicron in size and resides in pyrite or arsenopyrite. METHOD OF PREPARATION: Reject ore material was dried, crushed, pulverized and then passed through a 270 mesh screen. The +270 material was discarded. The -270 material was mixed for 5 days in a double-cone blender. Splits were taken and sent to 15 commercial laboratories for round robin assaying. Round robin results are displayed below: SAMPLE Lab 1 Au g/t Lab 2 Au g/t Lab 3 Au g/t Lab 4 Au g/t Lab 5 Au g/t Lab 6 Au g/t Lab 7 Au g/t Lab 8 Au g/t Lab 9 Au g/t Lab 10 Au g/t Lab 11 Au g/t Lab 12 Au g/t Lab 13 Au g/t Lab 14 Au g/t Lab 15 Au g/t GS-2M-1 GS-2M-2 GS-2M-3 GS-2M-4 GS-2M-5 GS-2M-6 GS-2M-7 GS-2M-8 GS-2M-9 GS-2M-10 2.21 2.20 2.23 2.24 2.14 2.28 2.17 2.16 2.30 2.33 2.29 2.25 2.27 2.38 2.26 2.37 2.29 2.22 2.25 2.28 2.17 2.21 2.08 2.11 2.14 2.19 2.16 2.13 2.02 2.20 2.14 1.88 1.74 2.00 2.14 2.15 1.79 1.84 2.09 2.04 2.40 2.24 2.28 2.33 2.37 2.29 2.21 2.44 2.44 2.45 2.07 2.14 2.12 2.20 2.06 2.02 2.08 2.18 2.00 2.12 2.19 2.21 2.20 2.24 2.22 2.05 2.18 2.27 2.11 2.14 2.45 2.34 2.32 2.50 2.47 2.51 2.29 2.33 2.44 2.49 2.06 2.06 2.03 2.03 2.16 2.12 2.11 2.01 2.16 2.15 2.13 2.03 2.12 2.14 1.97 2.02 2.02 2.18 2.27 2.19 1.88 2.02 1.89 2.05 2.00 1.96 2.07 2.09 1.90 1.99 2.45 2.46 2.36 2.45 2.25 2.44 2.23 2.43 2.40 2.29 2.26 2.14 2.49 2.29 2.31 2.27 2.44 2.22 2.22 2.20 2.16 2.22 2.20 2.23 2.20 2.15 2.23 2.19 2.23 2.21 2.19 2.30 2.27 2.33 2.20 2.16 2.25 2.17 2.21 2.20 Mean Std.

APPROXIMATE CHEMICAL COMPOSITION (by whole rock analysis): SiO2 Al2O3 Fe2O3 CaO MnO Total S Percent 81.7 7.6 1.8 0.7 <0.1 0.9 Na2O MgO K2O TiO2 LOI Percent 0.1 0.4 1.7 0.3 4.8 REFERENCE MATERIAL: CDN-GS-2M Statistical Procedures: The final limits were calculated after first determining if all data was compatible within a spread normally expected for similar analytical methods done by reputable laboratories. Data from any one laboratory was removed from further calculations when the mean of all analyses from that laboratory failed a t test of the global means of the other laboratories. The mean and standard deviation were calculated using all remaining data. Any analysis that fell outside of the mean ±2 standard deviations was removed from the ensuing data base. The mean and standard deviations were again calculated using the remaining data. This method is different from that used by Government agencies in that the actual “between-laboratory” standard deviation is used in the calculations. This produces upper and lower limits that reflect actual individual analyses rather than a grouped set of analyses. The limits can therefore be used to monitor accuracy from individual analyses, unlike the Confidence Limits published on other standards.
